The TPS3702 is an integrated
overvoltage and undervoltage window voltage detector in a small SOT-6 package. This
highly accurate voltage detector is an excellent choice for systems that operate on
low-voltage supply rails and have narrow margin supply tolerances. Low threshold
hysteresis options of 0.55% and 1.0% prevent false reset signals when the monitored
voltage supply is in the normal range of operation. Internal glitch immunity and
noise filters further eliminate false resets resulting from erroneous signals.
The TPS3702 does not require
any external resistors for setting overvoltage and undervoltage reset thresholds,
which further increases overall accuracy and reduces solution size and cost. The SET
pin is used to select between the two available threshold voltages designed into
each device. A separate SENSE input pin and VDD pin allow for the redundancy sought
by safety-critical and high-reliability systems. This device also features
independent reset outputs for the OV and UV pins; as a result of the open-drain
configuration, UV and OV can be tied together.
This device has a low typical
quiescent current specification of 7µA and is
qualified for use over the industrial temperature range of –40°C to 125°C.
